Water – Wastewater – Water Efficiency Conference Programme

      • 9:45 am - 10:00 amLiam McCarton, Sean O'Hogain - Lecturers, (WIRC) & (ESHI), DITPresentation Title: Nature Based Resource Recovery and the Circular Economy in Ireland. Presentation Synopsis: This presentation will review nature based solutions in water management and hydraulic infrastructure. The circular economy approach considers water and its contents as a resource. The discussion will present a number of case studies on resource recovery in nature based solutions.
      • 10:00 am - 10:15 amKieran Nolan - Head of School of Chemical Sciences, DCUPresentation Title: Novel Materials for Wastewater Treatment. Presentation Synopsis: There has been a growing awareness of the existence of micro-pollutants such as detergents, dyes, pesticides, herbicides and pharmaceuticals in the environment in recent years. At the same time, conventional ‎water and wastewater treatments such as adsorption, ozonation, UV and bio-degradation can only partially remove these micro-pollutants from treated water. Semiconductor photocatalysis using titanium dioxide (TiO2) has also been very well researched due to the potential of complete degradation of organic compounds and the minimization of waste disposal and energy consumption. However, TiO2 also has limitations, not least the requirement for UV light, which impede its application in an industrial wastewater treatment process. To overcome the disadvantages of TiO2, different TiO2 nanostructures (nanoparticle, nanotube, nanowire and mesoporous beads) were modified in a series of experiments with i) Dye functionalization of TiO2 and ii) with graphene to develop visible-light responsive TiO2-based photocatalysts. The effectiveness of the new composites were tested on a number of pharmaceuticals with graphene/TiO2nanotubes giving the best results. A graphene oxide sponge was also produced, which showed an exceptional adsorption capacity for the removal of a wide range of compounds (equilibrium reached in an hour) showing a higher efficiency than ‎that of activated carbon.
      • 10:15 am - 10:30 amBrendan Walsh – Chartered Engineer, UCCPresentation Title: An industrial water management value system framework. Presentation Synopsis: Global water demand is projected to increase through food production, manufacturing and electricity generation. Indeed, water, energy and food may actually be considered as one nexus on a worldwide scale. In industry, water performs many functions. Water efficiency programs have been undertaken for many years in different formats at several industrial locations. The one dominant outcome evident from all the studies is that the financial cost of the savings is not singularly adequate to justify the research, let alone the measures recommended. Employment of a methodology/framework, involving a Value System (VS) and a simulation model, demonstrates the application of Information and communications technology (ICT) to resource efficiency and thus may be used to assist in confronting necessary sustainability challenges. This talk shall outline such a proposed framework and discuss its implementation using an early-stage industrial case-study.
